It's more of a mechanical problem not an electronics problem, if you're talking about things like this electronics has very little to do with it. So what you need to do is sit and stare at it long enough thinking about what you're trying to do and coming up with possible solutions until one works. If you can't think of anything you need to mix things up and come at it from a different angle, until you find one that works for you. Just don't keep trying the same thing over and over again with microscopic changes if it's not working, and if you're drawing a complete blank talking it over with someone else even someone that isn't technically apt can help get the creative juices flowing, often simply talking allowed is enough to get the brain working because hearing what your saying lets your brain reprocess things.
